I am a mathematician and computer security scientist, with a strong interest in cryptography and anonymity, specialized in quantum security and complex cryptographic protocols. I am also a privacy hacktivist and public speaker, blahblahblah, read my Linkedin bio for this s**t, this is my Mastodon corner.
I co-develop Shufflecake, an open source privacy disk encryption tool to help journalists, activists, and whistleblowers evade unjust prosecution.
I am an advocate of digital self-sovereignty. You will see me often ranting about Big Tech, enshittification, and surveillance capitalism.
Fascinated with anime, Japan, RPGs, retro computing, and all things 80-90's. Notice I wrote "fascinated", not "knowledgeable".
Here you won't find peace nor forgiveness, but just: #cryptography #privacy #quantum #security #infosec #retro vibes!
There is literally zero reason why banking apps shouldn't work on GrapheneOS, and yet so many European financial institutions prefer to rely on the security assurances of megacorporations controlled by a foreign country.
At least I hope that the current geopolitical madness will contribute to stopping this plague.
Oh, this is so f***ing gold. This post is a juice concentrate of the many reasons why Matrix sucks:

Among others: > Users cannot be deleted > This is simply not an option in the API. Server admin can perform a "deactivate" (disable login) and "erase" (remove related data, which claims to be GDPR-compliant) on user accounts, but the accounts themselves stay on the server forever.
LOL.
Here is my take on why you should trash Matrix and use XMPP, or ta least Signal instead:
I wonder how meaningful canaries are, especially in the context of platforms like Mastodon. I mean, the bar to keep them alive is pretty high: "never provided any law enforcement organization logs/feed of our customers' content". I would expect these things to be the norm for a social media instance.
The war on crypto never ends. The war on privacy, civil rights, security and freedom of speech never ends.
This time we are dangerously close to lose. The "Child Sexual Abuse" (CSA) EU regulation proposal, more aptly nicknamed "ChatControl", will be voted AGAIN this October, and many countries who opposed it last year are now undecided. The proposal at its roots aims at allowing authorities to break end-to-end encryption for the usual reason: "because of the children". As a father of two, I am disgusted by this recurring, cheap rhetoric.
